The Primary Investigation of Ξ-N Skyrme Force Parameters

  • the parameters of Ξ–n skyrme force are firstly determined according to the experimental data.With these parameters,the Ξ–potential depth,the single particle energy and the root mean square radius of Ξ–hyperon(hypernucleus)are calculated in the skyrme–hartree–fock framework.the results agree well with those of other models.

Abstract: the parameters of Ξ–n skyrme force are firstly determined according to the experimental data.With these parameters,the Ξ–potential depth,the single particle energy and the root mean square radius of Ξ–hyperon(hypernucleus)are calculated in the skyrme–hartree–fock framework.the results agree well with those of other models.
